Abstract:
Methods and systems for manufacturing composite parts that include anodizable portions and non-anodizable portions such that an interface between the anodizable portions and non-anodizable portions are free of visible defects are described. The non-anodizable portions can be made of anodizable metals such as aluminum or aluminum alloy. The non-anodizable portions are made of material that do not generally form an anodic film, such as plastic, ceramic or glass materials. In particular, the methods described relate to manufacturing methods that are compatible with anodizing processes and avoid defects related to anodizing processes. In particular embodiments, the methods involve avoiding trapping of anodizing chemicals within a gap between an anodizable portion and a non-anodizable portion, which prevents the anodizing chemicals from disrupting the uptake of dye in a post-anodizing dyeing process.
Abstract:
Attachment systems (100) for attaching a wearable electronic device (102) to a user including a sizing band (106) and a retaining band (108) are disclosed. The sizing band includes at least one sizing eyelet (116) and a band-insertable end. The retaining band includes at least a post (114) for insertion into the sizing eyelet of the sizing band and a concealment aperture (110) configured to receive the band- insertable end of the sizing band. A bottom surface of the retaining band can be a recessed guide bed (112) configured to guide the band-insertable end along the bottom surface of the retaining band. A wearable electronic device can couple to both the sizing band and the retaining band by accepting an end portion (302a) of each band into receiving channels (324) extending into opposite sidewalls of the housing.
Abstract:
An enclosure and a method for forming an enclosure are disclosed. The enclosure may be formed from metal, such as aluminum, and further include a non-metal portion allowing for transmission and receipt of electromagnetic waves. The non-metal portion may be interlocked to the enclosure and in particular, to a region within the enclosure including a first material having a relatively high strength and stiffness compared to the non-metal portion. Interlocking means may include forming dovetail cuts into the enclosure to receive the non-metal portion, a hole or cavity drilled into the enclosure which includes internal threads, and a rod inserted into the first material to provide a tension to the non-metal portion. Methods of assembling internal components using anodization are also disclosed.
Abstract:
A system may have structure. The structures may include laminated structures formed by attaching inner and outer layers together with a layer of adhesive. The inner and outer layers in a structure may be formed from polymer such as polycarbonate. Forming the structure layers from polymer may allow the structure to have desired curvature. To improve safety and/or acoustic performance of the structure, the inner and outer structure layers may be formed from different materials. The outer polymer layer may be formed from polycarbonate and the inner polymer layer may be formed from a more brittle polymer such as polymethyl methacrylate (PMMA).
